I am blunt and to the point....No sugar coating. You have asked, so I will tell you what I think..... This guy needs to tell this "other" girl, who is married.....To get on with her life. The heck with the $ owed to him form the past, consider it a loss. He needs to tell her to leave him alone...Or, take out a restraining order. You sound like a really nice down to earth type person, and this "she needs a friend" crap gets real old real fast.....She can find another friend somewhere else. If this guy really cares about you and your emotions, he will get her out of the picture. Otherwise, I would move on. I say this, because if he doesn't stop this now, he never will. You do not need to have your heart broken. Life is too short....You should not have to deal with situations like this. There are too many other guys out there who would be devoted to you...And you alone! You are special....Remind yourself of this everyday. You play second fiddle to know one! Good luck sweeite, keep us posted!
